PETER COOK, OF TONAWANDA, NENV YORK.

MACHINE FOR CUTTING VENEERS.

Specification of Letters Patent No.

To all whom Lt may concern:

Be it known that I, PETER Coon, of Tonawanda` in the county of Erie and State of New York, have invented a new and Improved Machine for Cutting Veneers and also for Cutting Timber Into Boards for the Backs of Mirrors, Drawer-Bottoms, &c-; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l is a longitudinal vertical section of my improvement, (ai) (fr) Fig. 2 showing the plane of section. Fig. 2 is a plan or top view of ditto.

Similar letters of reference indicate coi responding parts in the two figures.

This invention consists in attaching a head or box in which the bolt is placed to a swinging frame which works over stationary cutters and over adjustable concave beds as will be hereinafter fully shown and described, whereby the bolt is fed to the knives by its own gravity and the veneers or boards cut from the bolt with the greatest facility and with but a small expenditure of power.

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

A represents a rectangular frame which may be constructed of either metal or wood. The upper part of this ,frame has curved flanches (a) (a) attached to it, two at each side, and B, B, are two concave beds, which may beof cast metal, which rest upon the flanches, (a) the beds B, extending the whole width of the frame, and the ends of the beds being secured to the lanches by screws (b). Set screws(c)also pass through the flanches for the purpose of allowing the beds to be adjusted at different heights. The beds B are formed of slats or bars (CZ) which are placed longitudinally with the framing, the bars (d) being connected to transverse bars (e) as shown in Fig. 2. The bars (el) and (c) may be cast in one piece. At the upper part of the frame A, and between the two beds B, B, two knives O, O, are secured. These knives are parallel with the inner ends of the beds, but the inner ends of the beds and the cutting edges of the cutters are not parallel with the outer ends of the beds, but are placed somewhat angularly or obliquely with them, see

16,529, dated February 3, 1857.

Fig. 2. The knives C, C, are secured permanently within the frame A and to cross bar (f). Each side of the frame A extends upward a suitable distance above the beds B, B, and a shaft D is fitted in bearings on the upper ends of the sides of the frame. To each end of the shaft D two arms (g) are attached, the lower ends of each pair of arms having a plate attached. Between the two plates (h) (7L) parallel plates or bars are secured, the ends of the plates litting in slots in the plates (la) and secured therein by screws The bars or plates (i) are parallel with the outer edges or ends of the beds B, B. The lower ends of the bars or plates are within a short distance of the upper surfaces of the beds B, B, and the shaft D is at such a height above the beds B, B, that as the bars or plates (i) are swung back and forth they will describe an arc corresponding to that formed by the beds B, B. To each plate (It) a connecting rod E is attached, the rods E being attached to cranks or wheels (le) arranged in any proper way for giving a swinging motion to the bars or plates The bolt E, shown in red, Fig. 1, is placed between two bars or plates which may be considered as a box or hollow head. The bolt F resting upon the beds B, B, the inner ends of which are placed somewhat below the cutting edges of the knives C, O, the space between the knives and beds corresponding to the desired thickness of the veneers or boards to be cut. The space between the cutting edges of the cutters and the inner ends of the beds may be regulated as desired by adjusting the screws (b) (c) so that veneers or boards of varying thickness may be cut.

As the bars or plates are moved back and forth over the beds B, B, a veneer or board is cut from the bolt F at each vibration or stroke, the veneers or boards passing down between the cutters and the inner ends of the beds, and as the bolt will always rest upon the beds, the bolt falling or settling by its gravity each time a veneer or board is cut from its lower surface, no feeding device is required, consequently the whole machine is rend-ed extremely simple and effective.

I am aware that machines for cutting staves have been previously used in which the cutters are moved in the arc of a circle, but machines of this kind differ essentially from mine. In the stave machines a feeding device is required to feed the bolt to the cutters, whereas in my machine no such device is necessary, as the bolt feeds itself to its work by its own gravity. In consequence of having the knives placed obliquely with the outer ends of the beds B, and plates or bars (i) (i) a drawing or oblique out is obtained.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is:

The swinging boX or head formed of the plates (i) (i) said boX or head working over concave beds B, B, and cutters C, C, when the above parts are arranged substantially as shown to allow the bolt F to feed itself to the cutters by its own gravity.

PETER COOK.
